Reference condition and different segmentation approaches for MV vortex ring extraction and analysis experiments. In the reference condition (A), manual segmentation was performed on short‐axis images throughout the entire cardiac cycle. The slice distance was increased (B) and the segmentation mask at end‐diastole was applied to all cardiac frames (C) to simulate segmentation speed‐up. The segmentation masks of all frames were eroded (D) and dilated (E) to simulate segmentation variability
